| Outline of Final Research Achievements |
In this study, we focused on mechanisms for formation and variability in oceanic frontal zones, which can be a key of air-sea interaction in midlatitude, the main theme of this “climate hotspot” project. Our studies have made significant improvements in our understanding of the formation and variability mechanisms in the Kuroshio and Kuroshio Extension, for example, mechanisms for the Kuroshio Large Meander to the south of Japan, and roles of submesoscale and mesoscale phenomena in the ocean and its ecosystem. Also, basin-scale atmospheric response over the North Pacific to decadal variability in the subarctic frontal zone in the western North Pacific is clearly shown in observed and simulated data. Further, heat capacity in the upper ocean in summer is revealed to be much larger than that has been considered. This finding can improve our understanding of the basic relationship between ocean and atmosphere in summer.
